3D Volumetric Voxel Display
by Lawrence D'Oliveiro 09 Sep '24

09 Sep '24

A guy from Weta Workshop has created a “volumetric voxel” display for showing 3D images, by spinning a regular 2D panel at a dizzyingly high speed (more than 300rpm). The images are fairly low-res: think 1980s pixelated graphics extended to the third dimension. <https://www.theverge.com/2024/9/6/24238004/doom-volumetric-voxel-display-an…> I hope it’s covered in some shield, not just to keep errant fingers (and other body parts away), but in case something ... um ... comes apart unexpectedly ...

Elasticsearch Will Be Open Source Again as CTO Declares Changed Landscape
by Peter Reutemann 04 Sep '24

04 Sep '24

'Elastic, creator of popular search engine Elasticsearch and visualization tool Kibana, plans to introduce the AGPL open-source license alongside its existing licenses. The move comes three years after Elastic ditched the Apache 2.0 license, sparking controversy in the tech community. Founder Shay Banon says the change aims to clarify Elastic's market position following AWS's creation of OpenSearch, a fork of Elasticsearch. Despite initial friction, Banon claims Elastic's relationship with AWS has improved, citing growth in Elastic Cloud revenue and customer base.' -- source: https://news.slashdot.org/story/24/09/03/0511245 Cheers, Peter

YubiKeys Are Vulnerable To Cloning Attacks Thanks To Newly Discovered Side Channel
by Peter Reutemann 04 Sep '24

04 Sep '24

'The YubiKey 5, the most widely used hardware token for two-factor authentication based on the FIDO standard, contains a cryptographic flaw that makes the finger-size device vulnerable to cloning when an attacker gains brief physical access to it, researchers said Tuesday. ArsTechnica: The cryptographic flaw, known as a side channel, resides in a small microcontroller that's used in a vast number of other authentication devices, including smartcards used in banking, electronic passports, and the accessing of secure areas. While the researchers have confirmed all YubiKey 5 series models can be cloned, they haven't tested other devices using the microcontroller, which is SLE78 made by Infineon and successor microcontrollers known as the Infineon Optiga Trust M and the Infineon Optiga TPM. The researchers suspect that any device using any of these three microcontrollers and the Infineon cryptographic library contain the same vulnerability. YubiKey-maker Yubico issued an advisory in coordination with a detailed disclosure report from NinjaLab, the security firm that reverse-engineered the YubiKey 5 series and devised the cloning attack. All YubiKeys running firmware prior to version 5.7 -- which was released in May and replaces the Infineon cryptolibrary with a custom one -- are vulnerable. Updating key firmware on the YubiKey isn't possible. That leaves all affected YubiKeys permanently vulnerable.' -- source: https://it.slashdot.org/story/24/09/03/1810216 Cheers, Peter

Microsoft Says Its Recall Uninstall Option in Windows 11 is Just a Bug
by Peter Reutemann 03 Sep '24

03 Sep '24

'While the latest update to Windows 11 makes it look like the upcoming Recall feature can be easily removed by users, Microsoft tells us it's just a bug and a fix is coming. Deskmodder spotted the change last week in the latest 24H2 version of Windows 11, with KB5041865 seemingly delivering the ability to uninstall Recall from the Windows Features section. "We are aware of an issue where Recall is incorrectly listed as an option under the 'Turn Windows features on or off' dialog in Control Panel," says Windows senior product manager Brandon LeBlanc in a statement to The Verge. "This will be fixed in an upcoming update."' -- source: https://it.slashdot.org/story/24/09/02/2241242 The only way to push a feature that users don't want: make it mandatory! I think, the technical term for this approach is "enshittification": https://en.wikipedia.org/wiki/Enshittification Cheers, Peter

Rust for Linux Maintainer Steps Down in Frustration With 'Nontechnical Nonsense'
by Peter Reutemann 03 Sep '24

03 Sep '24

'Efforts to add Rust code to the Linux kernel has suffered a setback as one of the maintainers of the Rust for Linux project has stepped down -- citing frustration with "nontechnical nonsense." The Register: Wedson Almeida Filho, a software engineer at Microsoft who has overseen the Rust for Linux project, announced his resignation in a message to the Linux kernel development mailing list. "I am retiring from the project," Filho declared. "After almost four years, I find myself lacking the energy and enthusiasm I once had to respond to some of the nontechnical nonsense, so it's best to leave it up to those who still have it in them." [...] Memory safety bugs are regularly cited as the major source of serious software vulnerabilities by organizations overseeing large projects written in C and C++. So in recent years there's been a concerted push from large developers like Microsoft and Google, and well as from government entities like the US Cybersecurity and Infrastructure Security Agency, to use memory-safe programming languages -- among them Rust. Discussions about adding Rust to Linux date back to 2020 and were realized in late 2022 with the release of Linux 6.1. "I truly believe the future of kernels is with memory-safe languages," Filho's note continued. "I am no visionary but if Linux doesn't internalize this, I'm afraid some other kernel will do to it what it did to Unix."' -- source: https://linux.slashdot.org/story/24/09/02/194205 Cheers, Peter

Public DNS Services
by Lawrence D'Oliveiro 02 Sep '24

02 Sep '24

So I finally got connected to fibre today, and I was pleased to discover that the ISP (https://simplybroadband.co.nz/) offers IPv6 as well. Is this common nowadays? We all know about the public DNS services offered by Google (8.8.8.8, 8.8.4.4) and Cloudflare (1.1.1.1, 1.0.0.1); did you know these addresses have names as well? And of course there are IPv6 addresses to go with the IPv4 ones. Try this command to find out all the related Google DNS services: host -a dns.google. (Yup, that’s “dns.google.”, no “.com” or anything else on the end.) That’s quite a breathtaking list of entries. For Cloudflare, try host one.one.one.one. Note that the “-a” option (“tell me everything”) doesn’t work with Cloudflare; quite a few online services are now imposing restrictions on these “all info” lookups, but clearly not Google, at least not on this domain: obviously they want it to remain easy for people to discover the services they’re offering.

Linux 6.12 To Optionally Display A QR Code During Kernel Panics
by Peter Reutemann 31 Aug '24

31 Aug '24

'A new feature has been submitted for inclusion in Linux 6.12, allowing the display of a QR code when a kernel panic occurs using the DRM Panic handler. This QR code can capture detailed error information that is often missed in traditional text-based panic messages, making it more user-friendly. The feature, written in Rust, is optional and can be enabled via a specific build switch. This implementation follows similar ideas from other operating systems and earlier discussions in the Linux community.' -- source: https://linux.slashdot.org/story/24/08/30/1856206 Cheers, Peter

Malware Infiltrates Pidgin Messenger's Official Plugin Repository
by Peter Reutemann 31 Aug '24

31 Aug '24

'The Pidgin messaging app removed the ScreenShareOTR plugin from its third-party plugin list after it was found to be used to install keyloggers, information stealers, and malware targeting corporate networks. BleepingComputer reports: The plugin was promoted as a screen-sharing tool for secure Off-The-Record (OTR) protocol and was available for both Windows and Linux versions of Pidgin. According to ESET, the malicious plugin was configured to infect unsuspecting users with DarkGate malware, a powerful malware threat actors use to breach networks since QBot's dismantling by the authorities. [...] Those who installed it are recommended to remove it immediately and perform a full system scan with an antivirus tool, as DarkGate may be lurking on their system. After publishing our story, Pidgin's maintainer and lead developer, Gary Kramlich, notified us on Mastodon to say that they do not keep track of how many times a plugin is installed. To prevent similar incidents from happening in the future, Pidgin announced that, from now on, it will only accept third-party plugins that have an OSI Approved Open Source License, allowing scrutiny into their code and internal functionality.' -- source: https://it.slashdot.org/story/24/08/30/2047211 Cheers, Peter

$50 2GB Raspberry Pi 5 comes with a lower price and a tweaked, cheaper CPU
by Peter Reutemann 30 Aug '24

30 Aug '24

'We're many months past the worst of the Raspberry Pi shortages, and the board is finally widely available at its suggested retail price at most sites without wait times or quantity limitations. One sign that the Pi Foundation is feeling more confident about the stock situation: the launch of a new 2GB configuration of the Raspberry Pi 5, available starting today for $50. That's $10 less than the 4GB configuration and $30 less than the 8GB version of the board. Raspberry Pi CEO Eben Upton writes that the 2GB version of the board includes a revised version of the Broadcom BCM2712C1 SoC that is slightly cheaper to manufacture. Upton says that the D0 stepping of the BCM2712C1 strips out some "dark silicon" built-in functionality that the Pi wasn't using but was still taking up space on the silicon die and increasing the cost of the chip. "From the perspective of a Raspberry Pi user, [the chip] is functionally identical to its predecessor: the same fast quad-core processor; the same multimedia capabilities; and the same PCI Express bus that has proven to be one of the most exciting features of the Raspberry Pi 5 platform," Upton writes. "However, it is cheaper to make, and so is available to us at somewhat lower cost. And this, combined with the savings from halving the memory capacity, has allowed us to take $10 out of the cost of the finished product." At $50, the price tag is still north of the baseline $35 price that the Pi started at for many years. The Pi 4 had a 1GB model for $35 when it launched, and there was a $35 2GB model available for a while in 2020, but widespread shortages and supply chain issues led to a "temporary" price increase in late 2021 that is, as of this writing, still in place. At least the 2GB Pi 5 is only $5 more expensive than the 2GB version of the Pi 4, which is still in stock for $45 at many retailers.' -- source: https://arstechnica.com/gadgets/2024/08/new-2gb-raspberry-pi-5-option-knock… Cheers, Peter
